HELP - Ecutek + PE 650 cc = LEAN Idle

Guys I really need your help. I just got some tuning done and got 250 whp with 17c turbo, greddy fmic, PE 650 cc and Ecutek. Why is it running lean between idle to about 4,000 rpm. If the injector size is set to 380 cc, then the idle is fine up to 4,000 rpm, them it just blows black smoke out the exhaust. Is this a dual stage injector? How can this be fixed on the Ecutek tuning? I am really bummed cause lots of $$ spent and not running safe.

PLEASE HELP ASAP!!

Do you have a stock fuel system with the 650cc injectors?

Also have walbro. Couldn't install SX FPR because at the time, no one had the AN fittings.

What is the impedence of the injectors vs. stock injectors?

I know the stock injectors are "high impedence" and thought there weren't many (any?) options over 560cc that were high impedence.
